FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication, and more particularly to techniques and apparatuses forrepetition configuration determination.

BACKGROUND

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, and/or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations(BSs) that can support communication for a number of user equipment(UEs). A user equipment (UE) may communicate with a base station (BS)via the downlink and uplink. The downlink (or forward link) refers tothe communication link from the BS to the UE, and the uplink (or reverselink) refers to the communication link from the UE to the BS. As will bedescribed in more detail herein, a BS may be referred to as a Node B, agNB, an access point (AP), a radio head, a transmit receive point (TRP),a new radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. New radio (NR), which may also bereferred to as 5G, is a set of enhancements to the LTE mobile standardpromulgated by the Third Generation Partnership Project (3GPP). NR isdesigned to better support mobile broadband Internet access by improvingspectral efficiency, lowering costs, improving services, making use ofnew spectrum, and better integrating with other open standards usingorthogonal frequency division multiplexing (OFDM) with a cyclic prefix(CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g.,also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) onthe uplink (UL), as well as supporting beamforming, multiple-inputmultiple-output (MIMO) antenna technology, and carrier aggregation.However, as the demand for mobile broadband access continues toincrease, there exists a need for further improvements in LTE and NRtechnologies. Preferably, these improvements should be applicable toother multiple access technologies and the telecommunication standardsthat employ these technologies.

DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully hereinafterwith reference to the accompanying drawings. This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based at least inpart on the teachings herein one skilled in the art should appreciatethat the scope of the disclosure is intended to cover any aspect of thedisclosure disclosed herein, whether implemented independently of orcombined with any other aspect of the disclosure. For example, anapparatus may be implemented or a method may be practiced using anynumber of the aspects set forth herein. In addition, the scope of thedisclosure is intended to cover such an apparatus or method which ispracticed using other structure, functionality, or structure andfunctionality in addition to or other than the various aspects of thedisclosure set forth herein. It should be understood that any aspect ofthe disclosure disclosed herein may be embodied by one or more elementsof a claim.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, and/or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

It is noted that while aspects may be described herein using terminologycommonly associated with 3G and/or 4G wireless technologies, aspects ofthe present disclosure can be applied in other generation-basedcommunication systems, such as 5G and later, including NR technologies.

FIG. 1 is a diagram illustrating a network 100 in which aspects of thepresent disclosure may be practiced. The network 100 may be an LTEnetwork or some other wireless network, such as a 5G or NR network.Wireless network 100 may include a number of BSs 110 (shown as BS 110 a,BS 110 b, BS 110 c, and BS 110 d) and other network entities. A BS is anentity that communicates with user equipment (UEs) and may also bereferred to as a base station, a NR BS, a Node B, a gNB, a 5G node B(NB), an access point, a transmit receive point (TRP), and/or the like.Each BS may provide communication coverage for a particular geographicarea. In 3GPP, the term “cell” can refer to a coverage area of a BSand/or a BS subsystem serving this coverage area, depending on thecontext in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). A BS for a macro cell may bereferred to as a macro BS. A BS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1, a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in theaccess network 100 through various types of backhaul interfaces such asa direct physical connection, a virtual network, and/or the like usingany suitable transport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1, a relay station 110 d may communicate with macro BS 110 a and aUE 120 d in order to facilitate communication between BS 110 a and UE120 d. A relay station may also be referred to as a relay BS, a relaybase station, a relay, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impact on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 Watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, e.g., directly or indirectly via a wireless orwireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, and/or the like. A UE may be a cellularphone (e.g., a smart phone), a personal digital assistant (PDA), awireless modem, a wireless communication device, a handheld device, alaptop computer, a cordless phone, a wireless local loop (WLL) station,a tablet, a camera, a gaming device, a netbook, a smartbook, anultrabook, medical device or equipment, biometric sensors/devices,wearable devices (smart watches, smart clothing, smart glasses, smartwrist bands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, such as sensors,meters, monitors, location tags, and/or the like, that may communicatewith a base station, another device (e.g., remote device), or some otherentity. A wireless node may provide, for example, connectivity for or toa network (e.g., a wide area network such as Internet or a cellularnetwork) via a wired or wireless communication link. Some UEs may beconsidered Internet-of-Things (IoT) devices, and/or may be implementedas may be implemented as NB-IoT (narrowband internet of things) devices.Some UEs may be considered a Customer Premises Equipment (CPE). UE 120may be included inside a housing that houses components of UE 120, suchas processor components, memory components, and/or the like.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT may also be referred to asa radio technology, an air interface, and/or the like. A frequency mayalso be referred to as a carrier, a frequency channel, and/or the like.Each frequency may support a single RAT in a given geographic area inorder to avoid interference between wireless networks of different RATs.In some cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure(V2I) protocol, and/or the like), a mesh network, and/or the like. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

As indicated above, FIG. 1 is provided merely as an example. Otherexamples are possible and may differ from what was described with regardto FIG. 1.

FIG. 2 shows a block diagram of a design 200 of base station 110 and UE120, which may be one of the base stations and one of the UEs in FIG. 1.Base station 110 may be equipped with T antennas 234 a through 234 t,and UE 120 may be equipped with R antennas 252 a through 252 r, where ingeneral T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI) and/or the like) and controlinformation (e.g., CQI requests, grants, upper layer signaling, and/orthe like) and provide overhead symbols and control symbols. Transmitprocessor 220 may also generate reference symbols for reference signals(e.g., the cell-specific reference signal (CRS)) and synchronizationsignals (e.g., the primary synchronization signal (PSS) and secondarysynchronization signal (SSS)). A transmit (TX) multiple-inputmultiple-output (MIMO) processor 230 may perform spatial processing(e.g., precoding) on the data symbols, the control symbols, the overheadsymbols, and/or the reference symbols, if applicable, and may provide Toutput symbol streams to T modulators (MODs) 232 a through 232 t. Eachmodulator 232 may process a respective output symbol stream (e.g., forOFDM and/or the like) to obtain an output sample stream. Each modulator232 may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively. According to variousaspects described in more detail below, the synchronization signals canbe generated with location encoding to convey additional information.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM and/or the like) to obtain received symbols. A MIMO detector 256may obtain received symbols from all R demodulators 254 a through 254 r,perform MIMO detection on the received symbols if applicable, andprovide detected symbols. A receive processor 258 may process (e.g.,demodulate and decode) the detected symbols, provide decoded data for UE120 to a data sink 260, and provide decoded control information andsystem information to a controller/processor 280. A channel processormay determine reference signal received power (RSRP), received signalstrength indicator (RSSI), reference signal received quality (RSRQ),channel quality indicator (CQI), and/or the like. In some aspects, oneor more components of UE 120 may be included in a housing.

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to basestation 110. At base station 110, the uplink signals from UE 120 andother UEs may be received by antennas 234, processed by demodulators232, detected by a MIMO detector 236 if applicable, and furtherprocessed by a receive processor 238 to obtain decoded data and controlinformation sent by UE 120. Receive processor 238 may provide thedecoded data to a data sink 239 and the decoded control information tocontroller/processor 240. Base station 110 may include communicationunit 244 and communicate to network controller 130 via communicationunit 244. Network controller 130 may include communication unit 294,controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform one ormore techniques associated with repetition configuration determination,as described in more detail elsewhere herein. For example,controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform or directoperations of, for example, process 900 of FIG. 9 and/or other processesas described herein. Memories 242 and 282 may store data and programcodes for base station 110 and UE 120, respectively. A scheduler 246 mayschedule UEs for data transmission on the downlink and/or uplink.

In some aspects, UE 120 may include means for receiving informationidentifying a channel configuration associated with a downlink channel;means for identifying a repetition configuration for the downlinkchannel based at least in part on the channel configuration; means formonitoring for the downlink channel in accordance with the repetitionconfiguration based at least in part on identifying the repetitionconfiguration; and/or the like. In some aspects, such means may includeone or more components of UE 120 described in connection with FIG. 2.

As indicated above, FIG. 2 is provided merely as an example. Otherexamples are possible and may differ from what was described with regardto FIG. 2.

FIG. 3A shows an example frame structure 300 for FDD in atelecommunications system (e.g., NR). The transmission timeline for eachof the downlink and uplink may be partitioned into units of radio frames(sometimes referred to as frames). Each radio frame may have apredetermined duration (e.g., 10 milliseconds (ms)) and may bepartitioned into a set of Z (Z≥1) subframes (e.g., with indices of 0through Z−1). Each subframe may have a predetermined duration (e.g., 1ms) and may include a set of slots (e.g., 2^(m) slots per subframe areshown in FIG. 3A, where m is a numerology used for a transmission, suchas 0, 1, 2, 3, 4, and/or the like). Each slot may include a set of Lsymbol periods. For example, each slot may include fourteen symbolperiods (e.g., as shown in FIG. 3A), seven symbol periods, or anothernumber of symbol periods. In a case where the subframe includes twoslots (e.g., when m=1), the subframe may include 2L symbol periods,where the 2L symbol periods in each subframe may be assigned indices of0 through 2L−1. In some aspects, a scheduling unit for the FDD mayframe-based, subframe-based, slot-based, symbol-based, and/or the like.

While some techniques are described herein in connection with frames,subframes, slots, and/or the like, these techniques may equally apply toother types of wireless communication structures, which may be referredto using terms other than “frame,” “subframe,” “slot,” and/or the likein 5G NR. In some aspects, a wireless communication structure may referto a periodic time-bounded communication unit defined by a wirelesscommunication standard and/or protocol. Additionally, or alternatively,different configurations of wireless communication structures than thoseshown in FIG. 3A may be used.

In certain telecommunications (e.g., NR), a base station may transmitsynchronization signals. For example, a base station may transmit aprimary synchronization signal (PSS), a secondary synchronization signal(SSS), and/or the like, on the downlink for each cell supported by thebase station. The PSS and SSS may be used by UEs for cell search andacquisition. For example, the PSS may be used by UEs to determine symboltiming, and the SSS may be used by UEs to determine a physical cellidentifier, associated with the base station, and frame timing. The basestation may also transmit a physical broadcast channel (PBCH). The PBCHmay carry some system information, such as system information thatsupports initial access by UEs.

In some aspects, the base station may transmit the PSS, the SSS, and/orthe PBCH in accordance with a synchronization communication hierarchy(e.g., a synchronization signal (SS) hierarchy) including multiplesynchronization communications (e.g., SS blocks), as described below inconnection with FIG. 3B.

FIG. 3B is a block diagram conceptually illustrating an example SShierarchy, which is an example of a synchronization communicationhierarchy. As shown in FIG. 3B, the SS hierarchy may include an SS burstset, which may include a plurality of SS bursts (identified as SS burst0 through SS burst B-1, where B is a maximum number of repetitions ofthe SS burst that may be transmitted by the base station). As furthershown, each SS burst may include one or more SS blocks (identified as SSblock 0 through SS block (b_(max_SS-1)), where b_(max_SS-1) is a maximumnumber of SS blocks that can be carried by an SS burst). In someaspects, different SS blocks may be beam-formed differently. An SS burstset may be periodically transmitted by a wireless node, such as every Xmilliseconds, as shown in FIG. 3B. In some aspects, an SS burst set mayhave a fixed or dynamic length, shown as Y milliseconds in FIG. 3B.

The SS burst set shown in FIG. 3B is an example of a synchronizationcommunication set, and other synchronization communication sets may beused in connection with the techniques described herein. Furthermore,the SS block shown in FIG. 3B is an example of a synchronizationcommunication, and other synchronization communications may be used inconnection with the techniques described herein.

In some aspects, an SS block includes resources that carry the PSS, theSSS, the PBCH, and/or other synchronization signals (e.g., a tertiarysynchronization signal (TSS)) and/or synchronization channels. In someaspects, multiple SS blocks are included in an SS burst, and the PSS,the SSS, and/or the PBCH may be the same across each SS block of the SSburst. In some aspects, a single SS block may be included in an SSburst. In some aspects, the SS block may be at least four symbol periodsin length, where each symbol carries one or more of the PSS (e.g.,occupying one symbol), the SSS (e.g., occupying one symbol), and/or thePBCH (e.g., occupying two symbols).

In some aspects, the symbols of an SS block are consecutive, as shown inFIG. 3B. In some aspects, the symbols of an SS block arenon-consecutive. Similarly, in some aspects, one or more SS blocks ofthe SS burst may be transmitted in consecutive radio resources (e.g.,consecutive symbol periods) during one or more slots. Additionally, oralternatively, one or more SS blocks of the SS burst may be transmittedin non-consecutive radio resources.

In some aspects, the SS bursts may have a burst period, whereby the SSblocks of the SS burst are transmitted by the base station according tothe burst period. In other words, the SS blocks may be repeated duringeach SS burst. In some aspects, the SS burst set may have a burst setperiodicity, whereby the SS bursts of the SS burst set are transmittedby the base station according to the fixed burst set periodicity. Inother words, the SS bursts may be repeated during each SS burst set.

The base station may transmit system information, such as systeminformation blocks (SIBs) on a physical downlink shared channel (PDSCH)in certain slots. The base station may transmit control information/dataon a physical downlink control channel (PDCCH) in C symbol periods of aslot, where B may be configurable for each slot. The base station maytransmit traffic data and/or other data on the PDSCH in the remainingsymbol periods of each slot.

As indicated above, FIGS. 3A and 3B are provided as examples. Otherexamples are possible and may differ from what was described with regardto FIGS. 3A and 3B.

FIG. 4 shows an example slot format 410 with a normal cyclic prefix. Theavailable time frequency resources may be partitioned into resourceblocks. Each resource block may cover a set to of subcarriers (e.g., 12subcarriers) in one slot and may include a number of resource elements.Each resource element may cover one subcarrier in one symbol period(e.g., in time) and may be used to send one modulation symbol, which maybe a real or complex value.

An interlace structure may be used for each of the downlink and uplinkfor FDD in certain telecommunications systems (e.g., NR). For example, Qinterlaces with indices of 0 through Q−1 may be defined, where Q may beequal to 4, 6, 8, 10, or some other value. Each interlace may includeslots that are spaced apart by Q frames. In particular, interlace q mayinclude slots q, q+Q, q+2Q, etc., where q∈{0, . . . , Q−1}.

A UE may be located within the coverage of multiple BSs. One of theseBSs may be selected to serve the UE. The serving BS may be selectedbased at least in part on various criteria such as received signalstrength, received signal quality, path loss, and/or the like. Receivedsignal quality may be quantified by a signal-to-noise-and-interferenceratio (SINR), or a reference signal received quality (RSRQ), or someother metric. The UE may operate in a dominant interference scenario inwhich the UE may observe high interference from one or more interferingBSs.

While aspects of the examples described herein may be associated with NRor 5G technologies, aspects of the present disclosure may be applicablewith other wireless communication systems. New radio (NR) may refer toradios configured to operate according to a new air interface (e.g.,other than Orthogonal Frequency Divisional Multiple Access (OFDMA)-basedair interfaces) or fixed transport layer (e.g., other than InternetProtocol (IP)). In aspects, NR may utilize OFDM with a CP (hereinreferred to as cyclic prefix OFDM or CP-OFDM) and/or SC-FDM on theuplink, may utilize CP-OFDM on the downlink and include support forhalf-duplex operation using TDD.

The ANC may be acentral unit (CU) of the distributed RAN 500. The backhaul interface tothe next generation core network (NG-CN) 504 may terminate at the ANC.The backhaul interface to neighboring next generation access nodes(NG-ANs) may terminate at the ANC. The ANC may include one or more TRPs508 (which may also be referred to as BSs, NR BSs, Node Bs, 5G NBs, APs,gNB, or some other term). As described above, a TRP may be usedinterchangeably with “cell.”

The TRPs 508 may be a distributed unit (DU). The TRPs may be connectedto one ANC (ANC 502) or more than one ANC (not illustrated). Forexample, for RAN sharing, radio as a service (RaaS), and servicespecific AND deployments, the TRP may be connected to more than one ANC.A TRP may include one or more antenna ports. The TRPs may be configuredto individually (e.g., dynamic selection) or jointly (e.g., jointtransmission) serve traffic to a UE.

As indicated above, FIG. 6 is provided merely as an example. Otherexamples are possible and may differ from what was described with regardto FIG. 6.

In some communication systems, such as 5G or NR, a BS may transmit aplurality of transmissions of a channel to a UE. For example, the BS maytransmit a first transmission of the channel and one or more repetitionsof the first transmission of the channel. The UE may receive theplurality of transmissions of the channel, and may combine the pluralityof transmissions to reconstruct the channel. In this way, the BS and theUE enable enhanced coverage for the network. However, when channelconditions are relatively good (e.g., pathloss between the BS and the UEis less than a threshold), the UE may not need to receive a plurality oftransmissions of a channel to reconstruct the channel. In other words,the UE may receive the first transmission of the channel, and determinedata conveyed by the channel without receiving any repetitions of thefirst transmission.

In this case, when the BS transmits a plurality of transmissions, the BSmay use excessive network resources for unnecessary repetitions.Similarly, under some channel conditions, a BS may transmit a firstquantity of repetitions of the channel to ensure the UE may reconstructthe channel, but the UE may be capable of reconstructing the channelusing a second, lesser quantity of repetitions of the channel, resultingin excessive user of network resources by the BS. In contrast, the BSmay transmit a first quantity of repetitions of the channel, but the UEmay not be capable of reconstructing the channel without a second,greater quantity of repetitions of the channel, resulting in poornetwork performance.

Some aspects, described herein, enable repetition configurationdetermination. For example, a UE may receive a channel configurationmessage associated with configuring a core resource set (CORESET), asearch space, and/or the like for a channel, and the UE may identify aparticular quantity of repetitions that the BS is to transmit to accountfor channel conditions based at least in part on a channelconfiguration. In this way, the BS may signal a quantity of repetitionsthat the BS is to provide, thereby enabling the BS to dynamicallyconfigure the quantity of repetitions based at least in part on channelconditions to achieve enhanced network coverage under relatively poorchannel conditions and reduced network resource utilization underrelatively good channel conditions.

FIG. 7 is a diagram illustrating an example 700 of repetitionconfiguration determination, in accordance with various aspects of thepresent disclosure. As shown in FIG. 7, example 700 includes a BS 110and a UE 120.

As further shown in FIG. 7, and by reference number 710, UE 120 mayreceive, from BS 110, channel configuration information for a physicaldownlink control channel (PDCCH). For example, UE 120 may receive aradio resource control (RRC) message identifying a CORESET for thePDCCH, a search space for the PDCCH, an aggregation level for the PDCCH,and/or the like. Additionally, or alternatively, UE 120 may receive adownlink control information (DCI) message associated with the PDCCH(e.g., a DCI associated with a particular format and identifying aresource allocation for the PDCCH).

As further shown in FIG. 7, and by reference number 720, UE 120 mayidentify a repetition configuration based at least in part on a channelconfiguration. For example, based at least in part on stored mappinginformation, UE 120 may determine that a particular CORESET (e.g.,CORESET 0, CORESET 1, and/or the like) is associated with a particularquantity of transmissions of the PDCCH. In this case, UE 120 maydetermine that the particular CORESET is associated with the particularquantity of repetitions based at least in part on stored informationidentifying a mapping of a plurality of CORESETs to a plurality ofquantities of repetitions. Additionally, or alternatively, UE 120 maydetermine that a particular search space (e.g., associated with aparticular periodicity) is associated with indicating a particularquantity of repetitions. Additionally, or alternatively, UE 120 maydetermine that a particular aggregation level is associated withindicating a particular quantity of repetitions. Additionally, oralternatively, UE 120 may determine that a particular DCI format of areceived DCI is associated with indicating a particular quantity ofrepetitions.

As further shown in FIG. 7, and by reference number 730, based at leastin part on determining the repetition configuration, UE 120 may monitorfor, and may receive one or more PDCCHs. For example, UE 120 maydetermine to receive a single transmission of the PDCCH, a plurality oftransmissions of the PDCCH, and/or the like. In this case, UE 120 mayreconstruct the PDCCH based at least in part on the one or more PDCCHs.For example, UE 120 may combine information associated with a pluralityof transmissions of the PDCCH to reconstruct the PDCCH under poorchannel conditions. In this way, BS 110 may signal, and UE 120 maydetermine a quantity of repetitions of a PDCCH, thereby enabling dynamicreconfiguration of the quantity of repetitions based at least in part onchannel conditions of a network.

As indicated above, FIG. 7 is provided as an example. Other examples arepossible and may differ from what was described with respect to FIG. 7.

For example, UE 120 may receivea first PDCCH associated with a first CORESET and a second PDCCHassociated with a second CORESET. As shown by reference number 820, UE120 may identify a repetition configuration based at least in part on achannel configuration. For example, based at least in part on storedmapping information, UE 120 may determine that a first physical downlinkshared channel (PDSCH) associated with the first PDCCH is associatedwith a first aggregation level based at least in part on the first PDCCHbeing associated with the first CORESET. Similarly, UE 120 may determinethat a second PDSCH associated with the second PDCCH is associated witha second aggregation level based at least in part on the second PDCCHbeing associated with the second CORESET.

In some aspects, UE 120 may determine a PDSCH repetition configurationbased at least in part on a PDCCH repetition configuration. For example,UE 120 may map a particular quantity of repetitions of a PDCCH to aparticular aggregation level for the PDSCH. Similarly, UE 120 may map aparticular PDSCH aggregation level to a particular PDCCH configuration(e.g., a particular PDCCH CORESET, a particular PDCCH repetitionconfiguration, and/or the like) to enable a PDSCH to be used to signalfor a subsequent PDCCH. In some aspects, UE 120 may determine a PDSCHrepetition configuration based at least in part on a received DCI, areceived media access control (MAC) control element (CE), a receivedtransmission configuration indicator (TCI), and/or the like.

As shown in FIG. 8B, and by reference number 830, UE 120 may monitorfor, and may receive one or more PDSCHs from the BS 110 based at leastin part on the repetition configuration. For example, UE 120 may receivethe first PDSCH associated with the first aggregation level in a singleslot based at least in part on the first aggregation level. Similarly,UE 120 may receive a plurality of slots of the second PDSCH associatedwith the second aggregation level based at least in part on the secondaggregation level. In this case, UE 120 may reconstruct the PDSCH basedat least in part on receiving the PDSCH. For example, UE 120 may combinethe plurality of slots of the second PDSCH to reconstruct the secondPDSCH. In this way, BS 110 may signal, and UE 120 may determine arepetition configuration relating to an aggregation level for a PDSCH.

As indicated above, FIGS. 8A and 8B are provided as an example. Otherexamples are possible and may differ from what was described withrespect to FIGS. 8A and 8B.
